Officially, Facebook says it has about 955 million monthly active users. However, as the company revealed this week in its 10-Q filing, it estimates that 8.7% -- or 83 million -- of those accounts
are fake. “That's a huge jump, both in raw numbers and as a percentage, from Facebook's last estimate,” CNet reports. “Back in March, Facebook said 5% to 6% of accounts are false or
duplicate. At the time, this meant between 42.25 million and 50.70 million users.” Why the jump? Facebook, to its credit, now appears to be doing a better job of identifying and classifying
fakes.
